HAROLD A. GL/DDEN BY 444 m! United States Patent WALL STRUCTURE AND FORM UNIT THEREFOR Harold A. Glidden, Berkeley, Calif.

Application September 25, 1957, Serial No. 686,141

3 Claims. (CI. 72-30) This invention relates to a building wall unit that is adapted to be used as a base unit in a wall and over which concrete or plaster may be placed in the construction of the wall.

An object of this invention is to provide an improved building wall unit employing a plurality of paper forms.

Another object of this invention is to provide an improved building wall unit employing folded paperforms that may be shipped in collapsed condition and easily assembled on the building site.

Still another object of this invention is to provide a building wall unit that may be assembled into the wall by persons having relatively little skill in such construction.

A further object of this invention is to provide an improved building wall unit with a plurality of bonding spaces into which wall surfacing plaster or stucco is adapted to be pressed so as to produce a wall structure of increased strength.

Still another object of this invention is to provide an improved building wall unit in which the bonding spaces receiving the surface plaster or stucco allow the forming of partial webs which give strength to the wall.

Still another object of this invention is to provide an improved building wall unit to which wall faces may be placed with gunite type machines or plaster guns.

Still another object of this invention is to provide an improved building wall unit employing paper core blocks which may also be used to make the corners of a wall and which eliminate all mold and equipment ordinarily required for applying surfacing to wall corners.

Other and further objects of this invention will be apparent to those skilled in the art to which it relates from the following specification, claims and drawing.

In accordance with this invention there is provided an improved building wall unit that is made of paper such as common water proof building paper which is formed in rectangular or square cells that are arranged in the unit in parallel spaced relation so that plaster or stucco may be applied thereto and bonded to the building unit by webs formed by the plaster or stucco entering the spaces provided between the individual cells.

These cells are held together by means of channel members which are also formed of water proof building paper and which are adapted to receive mortar as well as reenforcing members in the channels thereof.

The building wall units of this invention are constructed so that the bottom channel of one unit may be placed upon the top channel of another unit and the mortar in these channels may be formed into an integral beam with reenforcing members lodged therein' The end cells of each of the wall units may be filled with mortar and vertical reenforcing members may be provided thereto so as to extend from one building wall unit to another on vertical alignment therewith.

Further details of this invention will be apparent to those skilled in the art to which it relates from the following specification, claims and drawing in which briefly:

Fig. 2 is a view of one of the channel members such as are employed for holding the tops and bottoms of the square or rectangular box units of an embodiment of this invention in assembled relation;

Fig. 3 is a view showing a plurality of the box units assembled in parallel spaced relation and having the bottom ends thereof fastened to a channel member and showing the top portions thereof positioned to receive the top channel member;

Fig. 4 is a detail sectional view taken along the line 44 of Fig. 3;

Fig. 5 is a perspective view partially in section showing several of the assembled box units such as shown in Fig. 3 positioned side by side in a wall structure partially covered with plaster or stucco;

Fig. 6 is a sectional view taken along the line 6-6 of Fig. 5;

Fig. 7 is a view of a modified embodiment of this invention;

Fig. 8 is a view of a further modification of this invention; and

Fig. 9 is a view of a portion of the structure shown in Fig. 8 somewhat enlarged.

Referring to the drawing in detail there is shown in Fig. 1 an element 10 constructed of paper folded along the scores 10 so as to form a box element or unit that is illustrated in collapsed condition. This box element is provided with additional scores 10" along which it may be folded in order to erect the element and provide the box of hollow square shape. The end portions 10a and 10b of this element overlap and are joined together by glue, cement, wire clips and the like. Tabs are provided to two of the panel members of the element at one of the ends of said panel members and tabs 10d are provided to corresponding panel members at the other ends thereof. Fig. 2 illustrates a channel member 11 and a pair of such members is employed to hold a plurality of box units 10 assembled. This member is provided with side portions 11a and 111; which are adapted to be folded so as to extend at right angles with respect to the body portion of the channel member. Holes 11c and 11d are provided to the end portions of the channel member ll. A channel member such as that shown in Fig. 2 is adapted to be employed to hold the top portions of a plurality of elements or boxes such as shown in Figure 1 in spaced relation. A similar channel member 12 which is identical to the member 11 is employed for a similar purpose at the bottom of the assembled elements.

The erected elements 10 are arranged with the side tabs 10d thereof extending over the outside of the side members 11a and 11b of the top channel 11 and the side tabs 100 at the bottoms of the elements 10 are similarly arranged with respect to the side walls 12a and 12b of the bottom channel 12. The bottom tabs 100 are shown attached to the side walls of the channel 12 by means of wire clips 13 and similar clips are employed for attaching 11a and 11b of the top channel 11. In this way the erected elements 10 are held in parallel spaced relation between the channel members 11 and 12 so that small spaces 14 are provided between adjacent units 10. These spaces 14 are adapted to receive plaster or stucco whereby webs thereof are formed be tween the units 10 and these webs function to increase the tenacity with which the plaster or stucco grips the building unit.

After the elements 10 are assembled with the channel members 11 and 12 to form a. building unit a small amount of mortar may be lodged in these channel meznv Patented May 26, 1959,

bers 11 and 12 as shown in Figure 4 and this functions to increase the rigidity of the individual building unit particularly after the mortar is allowed to set slightly. The unit thus provided with mortar is easier to handle during the construction of a wall.

In Fig. 5 there is shown a building wall made by placing two of the assembled units of the type shown in Fig. 3 one above the other and coating these units with an outer layer 18 of mortar, such as, plaster or stucco. The mortar enters the slots 14 between the boxes and because these boxes are of paper, such as, building paper, tar paper and the like, the mortar wedges itself in against the sides of the slots 14 which yield slightly so that the mortar entering these slots assumes a keystone shape and after it sets it is locked in position because of this feature. While only two of the units are shown in Figure 5 it is of course obvious that additional units may be placed one above the other as desired to make a wall of different heights. When these units are placed into position one upon the other the channels 11 and 12 are provided with additional mortar and a reenforcing rod 16 of steel or a plurality of such rods may be lodged into the mortar 15 to form a reenforced mortar beam. Similar reenforcing members of steel or the like may be placed into the end boxes of the building unit through the holes 11c and 11d provided in the end portions of the channel member 11 and through similar holes provided in the end portions of the channel member 12. These end boxes are filled with mortar which surrounds the reenforcing members 17, thereby forming reenforced vertical columns at spaced intervals in the wall structure. These vertical reenforced columns are of course made integral with the horizontal reenforced beams formed by the mortar 15 and horizontal reenforcing member 16. In this way a wall structure having considerable strength is provided around the basic unit made up of the folded building paper elements described.

Where the Wall structure shown in Fig. 5 is to form a corner of the wall or where another wall is to be joined thereto or abut therewith it may be desirable to join or tie the corner wall or abutting wall to that shown in Fig. 5 by means of reenforcing rods 16a which are positioned in the corner or abutting wall in the same manner as the rods 16 are positioned in the wall illustrated. The rods 16a enter the tops of the boxes 10 through cutaway portions 16b and the corner or abutting walls is constructed in the same way as the wall illustrated. A small mortar receiving slot such as the slot 14, may be provided between the boxes 10 and the corner or abutting wall to receive some of the covering mortar.

From the above description it will be seen that the form unit as disclosed herein provides for a desirable wall construction of light weight where the form unit may be employed to initially support the wet concrete for a steel reenforced concrete beam as the load supporting structure of the wall or other structure and the form unit itself providing for a light weight structure when load supporting characteristics are required. The wall can be erected without exterior mortaring and with a minimum of skilled labor so that cost is materially reduced. If desirable the two faces of the form unit may be finished with different characteristics, for exampl, one surface which is to function as an outside wall may be colored or otherwise decorated and the inner surface which is to function as an inside wall may be scored or roughened to receive plaster. Also the inner face of the unit may be made of lighter construction and the outer face of the unit may be made heavier as desired or required for a particular construction.

In Fig. 7 there is illustrated another embodiment of this invention in which the box units 20. of tubular type are placed in a vertical positon similar to that shown in Fig. 5 and a number of these boxes are also placed side by side to receive concrete, faces. However in this embodiment the boxes may be provided with a suitable aperture for placing of horizontal ,reenforcing rods 24 therein and preferably the faces project beyond one end of the box to provide a nesting of the form units with multiple boxes as shown. For this purpose each box is provided with lateral extensions 21 and 22 which overlap the next adjacent box so that the boxes may be joined by a cement or other bond that is applied to the inner surface of the overlapping portions or tabs 21 and 22 so as to bond the boxes together as a unit and provide a water proof layer on the face to be used in exposure to the weather. If desired, only one side of the boxes may be provided with such tabs or flanges so as to provide a weather proof layer on only one side of the unit which of course is the outer side of the wall. Furthermore, the units may be provided with a steel wire or net reenforcing 23. Also if desired the openings provided by each box in this type of unit may be filled with concrete and one or more reenforcing members such as the rod 25 may be placed therein, so as to provide a concrete wall structure of full extent when completed. On the other hand only certain of these longitudinal openings may be filled as may be required by the type of wall construction.

In Figs. 8 and 9 there is illustrated another modified form of this nvention in which an assembled self-supporting unit of form boxes 26 of building paper, tar paper and the like, is provided, which includes a plurality of such open ended boxes. These boxes are square or rectangular in cross section when made but are compressed slightly to provide convex side walls 27, one of which includes the stapled overlapping portions held together by wire staples 29 or the like. Additional strips 31 may be provided to the convex sides of the boxes and these strips may be attached to these sides by suitable cements.

The number of boxes to form an assembly, six in number, as shown in Figure 8, are placed side by side with a concrete bonding layer 33 interposed in the compressed condition of these boxes. Because of the convex side walls, it will be noted that V-shaped recesses are provided at each juncture of the boxes for future bonding to a face of concrete. The boxes are held together, in addition to the concrete bond therebetween, by a plurality of Wrap around strips 39 preferably formed of asphalt coated fiberglass cloth. Each fiberglass strip is bonded to the boxes by concrete grouting 34 at each juncture that the strip overlies.

This assembled core unit or body unit provides a light easily transported member which can be laid flat on the job and have a cement face applied to one or more of its sides. Alternatively the cement face can be applied in the manufacture before shipment.

With respect to the various form of the box, it is seen that a form unit of standard size and construction is shown which in effect may be termed a modular unit so that a plurality of these may be employed in erecting a wall, or building a. fence, etc. These modular units lend themselves to economical production and case of assembly in erecting the wall structure at its site.

While the use of building paper and tar paper has been described, it is obvious that the boxes 1%, 2t] and 26 may be made of sheet plastic, fiber board, corrugated paper, molded pulp sheet and any other sheet materials of light weight, and it is not desired to limit this invention solely to the use of building or tar paper.

This application is a continuation in part of my application, Serial No. 449,452, filed August 12, 1954.
